Hi, sorry to ask again, an java.lang.Security Exception is thrown after
starting the installer. It states an invalid signature file in the manifest.
I have looked into the jar file. From my point of view the merging of the
jars is correct. Due to the fasct, that I use xerces the path org/apache is
used by both jars, xecres and Jakarta-regexp.jar. Might this cause the
problems? If I take another jar that only shared com/ there is no error.

Hi Klaus,
if you need some classes of a jar file in a custom panel/action
and the class names are unique add following entry after the
<packs> entry into your install.xml.

<jar src="$BuildRoot/subPath/my.jar" stage="install"/>

See "The Jar Merging Element <jar>" in the docu.
The path has not to be relative to the IzPack root else to the path
where your files to be installed are.
